About Converting Sections to Square feet
Comparing Section and Square foot is common in agriculture and real estate, where US land is typically measured in acres and most of the rest of the world uses hectares. Specifically: A US public land survey section is one square mile or 640 acres, and a square foot is exactly 0.09290304 square meters.
Formula
square feet = sections × 27878400
This factor comes from each unit's defined relationship to the category's base unit: 1 section equals 2589988.11034 base units, and 1 square foot equals 0.09290304 base units, so dividing one by the other gives the direct section-to-square foot factor of 27878400.
Simple example
1 section × 27878400 = 27,878,400 ft2
1 section = 27,878,400 square feet.
